Design And Implementation Of Online Monitoring System Of Intelligent Seedling Boxes Based On Cloud Computing

With the rapid development of the Internet of Things and cloud computing technology,its applications have involved all aspects of our lives.Modern agricultural production has also seen the application of technologies such as cloud computing.In some areas of China,there has been a certain amount of intensive seedlings,but it still needs the help of manual operations.The seedling raising technology needs further improvement.This topic has designed an intelligent nursery box on-line monitoring system that can be used to cultivate high-quality seedlings.The system consists of three parts: nursery box data acquisition and control terminal,cloud server,and communication module.Acquisition and control terminals are divided into two parts: data acquisition and data control.The STM32F767IGT6 microprocessor is used as the main control chip.The data acquisition module collects temperature and humidity,soil moisture,light intensity,ozone and carbon dioxide gas concentration in the nursery box through each sensor and displays the data in real time on the RGBLCD screen.The micro controller compares the data collected by the sensor with the set parameter thresholds,and controls the parameters in the nursery box through the regulation of the heating film,roller shutter,exhaust fan,irrigation device,ozone generator and other equipment.The STM32 uploads the collected data information to the cloud server through the GPRS wireless transmission module.The server uses the cloud computing service to store the received data in the cloud.Use the Visual Studio 2015 integrated development environment to design the cloud server monitoring and management platform.The software receives data uploaded by the data acquisition terminal through network communication,and after data analysis and processing,it is presented to the management interface in the form of curves and numbers,according to the actual growth of crop seedlings.The required parameter thresholds can be set,and the software also supports historical data query functions.Combined with the environmental control requirements of the nursery box,PID control algorithms are used to process the data to improve the stability and reliability of the system.This system combines embedded technology,wireless communication technology,and sensor technology to realize intelligent management of environmental factors in nurseryboxes.The PID control algorithm is used to control the environmental parameters so that the parameter values can quickly reach the preset range and the stability of the system is improved.Cloud computing technology is used to build servers,which reduces system development costs and makes system maintenance easier.The design selects different crops to carry on the nursery experiment to carry on the test to the system function,through many experiments test can obtain,the overall system stability is high,the survey data is accurate.
